Ukukhetha komthombo ofanele we-laser

Ukukhetha okuhleumthombo we-laser: Edge Emission Semiconductor Laser
1. Isingeniso
I-Semiconductor LaserAma-chips ahlukaniswe ngama-Edge akhipha ama-LASER CHIPS (EEL) kanye ne-vertical cavity survity ekhipha ama-laser chips (vcsel) ngokwezinqubo zokukhiqiza ezihlukile ze-resonators, ukukhishwa okuqondile kwe-semiconductor laser, ephuma e-semiconductor technology technology kuvuthiwe ngokwengeziwe, okuphezuluI-Electro-OpticalUkusebenza kahle, amandla amakhulu nezinye izinzuzo, ezilungele kakhulu ukucubungula ama-laser, ukuxhumana kwe-Optical nezinye izinkambu. Njengamanje, ama-semice-emfingfit seconductor lasers ayingxenye ebalulekile yemboni ye-opoleelectronics, futhi izicelo zawo zibe nemikhakha embozwe, ukuxhumana ngocingo, isayensi, umthengi, umthengi kanye ne-aerospace. Ngokuthuthuka kanye nenqubekela phambili yezobuchwepheshe, amandla, ukuthembeka kanye nokuguqulwa kwamandla kokuguqulwa kwamandla kwama-semiconductor ama-semiconductor ama-semiconductor athuthuke kakhulu, futhi amathemba abo okufaka answ an kakhulu.
Okulandelayo, ngizokuholela ekuqhubekeni nokwazisa ubuhle obuhlukile bokukhiphaAma-Semiconductor Lasers.

2. Ukusebenza komgomo we-Edge Engimission semissiolctori-laser
Ukwakheka kwe-semiconductor ye-semiconductor ye-semiconductor kungahlukaniswa izingxenye ezintathu ezilandelayo: Umthombo we-semiconductor, umthombo wepompo kanye nomthengisi obonakalayo. Okuhlukile kubathengisi be-vertical cavity surving ama-lasers (akhiwa izibuko eziphezulu nangaphansi ze-Bragg), ama-resonators e-semicit-efit-emfingfit semicenductor amadivaysi abhalwa amafilimu abonayo zombili izinhlangothi. Isakhiwo se-eel esijwayelekile se-eel sesakhiwo kanye nesakhiwo se-resonator sikhonjiswa kuMfanekiso 2. I-Photon ku-Edge-Emion-Emiction Semiconductor Idivayisi ye-Edlified ngokukhethwa kwemodi ku-resonator, futhi i-laser yakhiwa endaweni ehambelana ne-substrate. Amadivayisi we-Semig-Emit Semiconductor Laser anezinhlobonhlobo zama-wavelength ahlukahlukene futhi alungele izinhlelo eziningi ezisebenzayo, ngakho-ke ziba ngomunye wemithombo ekahle ye-laser.

Izinkomba zokuhlola ukusebenza kwama-semictonductor ama-semiconductor ama-semiconductor ahambisana namanye ama-lasessonductor ama-lasers, kufaka phakathi: (1) i-laser lasing wavelength; (2) umkhawulo okhona njengamanje, okungukuthi, okwamanje lapho i-laser didoode iqala ukukhiqiza i-laser oscillation; . (4) ukusebenza kahle kwethambeka; (5) vertical divergence angle eng θ⊥; (6) i-angle enezingqimba Divergence eng θ∥; (7) Gada i-IM yamanje, okungukuthi, usayizi wamanje we-semiconductor laser chip kumandla okukhishwa alinganiselwe.

I-3. Inqubekela phambili Yokucwaninga Kwama-Gaas kanye noGan based Edge ikhipha ama-semiconductor lases
I-Semiconductor Laser esuselwa ku-Gaas Semiconductor Material ingenye ye-semiconductor laser technologies. Njengamanje, i-gaas esekwe eduze kweqembu le-inf-infrared (760-1060 nm) ama-seconductor ama-semiconductor ama-semiconductor asetshenziswa kabanzi kwezentengiso. Njengesizukulwane sesithathu semiconductor ethe xaxa ngemuva kwe-SI ne-GAAS, uGan ubekhathazeke kabanzi ocwaningweni lwesayensi nasembonini ngenxa yezakhiwo zawo ezinhle kakhulu nangamakhemikhali. Ngokuthuthukiswa kwamadivayisi we-Optoelectonic asuselwa ku-GAN kanye nemizamo yabacwaningi, ama-diode asuselwa ku-gan-based emzimbeni kanye nama-lasers akhipha ama-odge athuthukile.
